I don't get how anyone can put Sakura on the list. No one likes her. How can she be overrated? If you hate her so much put her in a hated characters list, not an overrated one. It's pretty tiring.
Anyway, my character is Yuno Gasai from Mirai Nikki. DEAR GOD, I HATE THIS BITCH.
Minene is the only good character in that entire show.
I'm not too big on Mami from Madoka Magica either. The only reason she's so popular is because she died and has tits. She's one-dimensional and boring, IMO.
I don't hate them, but Sena and Kobato from Boku wa Tomodachi ga Sukunai are grossly overrated.

Sakura may be useless but at least she doesn't destroy every arc she's featured heavily in like Sasuke has ever since part 2 started, i also really hated Yoshito from Beck and loved when Koyuki punched him in the manga, Near from Death Note is what you would get if you took L and sucked out everything that made L cool while simultaneously making him a white haired midget, Shirou from Fate/Stay Night pisses me off and he didn't deserve Saber, and Sayaka from Madoka Magica was basically what you would get if you crossed Shinji and Asuka from Evangelion arrogant yet emo

Yuno Gasai from Mirai Nikki really bugged the hell out of me. She was so caught up in her child-like fantasy of romancing Yuki that she was willing to kill anyone that even tried to get close to him and later locked him up and nearly starved him to death all to "protect" him. I don't care how terrible her backstory is, nothing justifies her actions.
